Why does saturation current mean?
Saturation-current definition (physics) The maximum current that can be obtained in a specific circuit under specified conditions.
What is saturation current in photoelectric effect?
The maximum value of the photoelectric current is called the saturation current. Saturation current implies that all the photoelectrons emitted by the emitter are immediately collected by the anode.
What is saturation current formula?
Hint: We know that the current that flows in reverse bias PN junction diode is called reverse saturation current. From the diode current equation I=Is(eVηVT−1) the current should decrease as the temperature is increased but the opposite happens.
What is saturation current class 12?
Solution : The maximum value of photoelectric current obtained by increasing the accelerating positive potential is called saturation current. Saturation current is proportional to intensity of incident radiation.
What is saturation current in diode?
The saturation current is a combination of the generation current caused by thermal generation of electron hole pairs within the depletion region of the diode and the diffusion current due to minority carriers in the n and pregions diffusing across the depletion region.
What is saturation current in a diode?
What is saturation current density?
The saturation current density of an emitter Jo represents the sum of all the recombination mechanisms inside the emitter. It includes the SRH, surface, contact and Auger recombination mechanisms, as well as heavy doping effects such as bandgap narrowing.
What happens when core saturates?
A.k.a. “transformer saturation.” A condition where a transformer’s core is fully magnetized and is producing maximum magnetic flux. This typically happens when the transformer is not large enough for the application.
